What will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?
Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the mirror.
How magnification of a convex mirror is always Positive and its magnitude is less than 1?
The magnification of a convex mirror is always positive because the image formed is virtual and upright. The magnification is less than 1 because the image is diminished in size compared to the object. This is due to the diverging nature of convex mirrors, causing the rays to spread out and create a smaller image.
What is the relation between speed of image and speed of object in a convex mirror?
In a convex mirror, the speed of the image is always less than the speed of the object. This is because the reflected rays diverge and appear to be coming from a point behind the mirror, causing the image to appear smaller.
How rubbing a mirror with sandpaper will affect how the mirror reflects light.?
Rubbing a mirror with sandpaper will scratch its surface and create tiny imperfections. These scratches will scatter the light that hits the mirror, resulting in a less clear and distorted reflection compared to a smooth, unscratched mirror.
Does a thin convex lens concentrate light more than a thicker lens?
Yes, a thin convex lens will concentrate light more effectively than a thicker lens because it brings the light rays to a sharper focus due to its shape. Thicker lenses have a less aggressive curvature, which can lead to a less precise focus and more dispersion of light.

What are the two kind of mirror in compound microscope?
Convex - which is the flat or the plain mirror and it has the lesser lights to receivebut its has the more light intensity.Concave - which is the curve mirror where the lights to receive is more than the convexbut it has the less light intensity.
Plane mirror convex or concave mirror which is best for bicycle mirror?
I use a mirror with a slight convex curve - like the outside of a spoon, but a lot less bent. But it's hard to find a good one. If you fasten a flat mirror most places on a bicycle, the mirror image will shake around so you can't see it. Also, in a convex mirror, you can see more of the road. But if it's too much bent, too round, then the image is distorted and you can't judge where a vehicle in the mirror really is. The last mirror I bought was described as convex, but actually is flat, so I'm planning to get a piece of car mirror glass cut by a glazier to fit in the frame. That glass is just a little convex.

What is the magnification factor for convex mirror?
The magnification factor (m) for a convex mirror is defined as the ratio of the image height (h') to the object height (h), expressed as ( m = \frac{h'}{h} ). For a convex mirror, the magnification is always positive and less than 1, indicating that the image is virtual, upright, and smaller than the object. The formula for magnification can also be expressed in terms of the object distance (u) and the image distance (v) as ( m = -\frac{v}{u} ), where both v and u are negative for a convex mirror.

How many seconds does light travel?
less than a second if a mirror a second
What is a one-way mirror and how does it work?
A one-way mirror, also known as a two-way mirror, is a special type of mirror that allows light to pass through from one side while reflecting light on the other side. This creates the illusion of transparency on one side and reflection on the other. The side with more light will see through the mirror, while the side with less light will see only their reflection. This effect is achieved by controlling the amount of light on each side of the mirror.
What is a convex pentagon?
it is a shape with 180degrees or less
Are convex angles less than 90 degrees?
A convex angle is any angle of 180 degrees or less. So all angles less than 90 degrees are certainly convex angles, but so are the angles between 90 and 180 degrees.
